Compressors, Gas Turbines and Jet Engines The clearance volume of the air compressor is kept minimum because It greatly affects volumetric efficiency It allows maximum compression to be achieved It permits isothermal compression It results in minimum work It greatly affects volumetric efficiency It allows maximum compression to be achieved It permits isothermal compression It results in minimum work ANSWER DOWNLOAD EXAMIANS APP
Compressors, Gas Turbines and Jet Engines The indicated work per unit mass of air delivered is Greatly affected by clearance volume Directly proportional to clearance volume Inversely proportional to clearance volume Not affected by clearance volume Greatly affected by clearance volume Directly proportional to clearance volume Inversely proportional to clearance volume Not affected by clearance volume ANSWER DOWNLOAD EXAMIANS APP
Compressors, Gas Turbines and Jet Engines Isothermal compression efficiency, even when running at high speed, can be approached by using Both (A) and (B) above Fully insulating the cylinder Cold water spray Multistage compression Both (A) and (B) above Fully insulating the cylinder Cold water spray Multistage compression ANSWER DOWNLOAD EXAMIANS APP
Compressors, Gas Turbines and Jet Engines The overall isothermal efficiency of the compressor is defined as the ratio of Work required to compress the air isothermally to the actual work required to compress the air for the same pressure ratio Isothermal power to the shaft power or B.P. of the motor or engine required to drive the compressor Volume of free air delivery per stroke to the swept volume of the piston Isentropic power to the power required to drive the compressor Work required to compress the air isothermally to the actual work required to compress the air for the same pressure ratio Isothermal power to the shaft power or B.P. of the motor or engine required to drive the compressor Volume of free air delivery per stroke to the swept volume of the piston Isentropic power to the power required to drive the compressor ANSWER DOWNLOAD EXAMIANS APP
